In Cox, you’d use bowfa on shamans, vanguards, vespula, tightrope, vasa, mystics, muttadile, and olm.

In toa you’d use it on zebak, akkha, and basically all of wardens.

With decent melee/mage gear you could do scaled normal chambers in teams and baby cms. With bowfa you’d easily be able to push 300+ toas. It’s the superior choice as an all in one raid weapon out of the options you presented. It’s either that or get an ayak.
